Marriage networks in the 'Ndrangheta mafia reveal that moderate bride reception, not just powerful clans, strengthens organizational cohesion and resilience. Peripheral alliances are as crucial as those of dominant families for stability.
Area of Science:
- Sociology
- Criminology
- Network Analysis
Background:
- The Italian mafia, specifically the 'Ndrangheta, is a complex criminal organization.
- Understanding the internal dynamics, power structures, and cohesion mechanisms of such organizations is crucial for effective law enforcement and social science research.
- Matrimonial ties have been historically observed as a strategy for alliance-building and power consolidation in various social structures, including organized crime.
Purpose of the Study:
- To analyze the relationship between marriage patterns and power/cohesion within the 'Ndrangheta.
- To investigate whether matrimonial ties serve as an organizational technology for enhancing network resilience and managing power dynamics.
- To test the 'bride-receiving' narrative and explore gendered exchange patterns in relation to clan influence.
Main Methods:
- Utilized judicial records detailing 770 inter-clan alliances and 906 marriages among 623 'Ndrangheta clans.
- Applied network analysis to map clan positions and centrality within the marriage network.
- Simulated the removal of marriage ties to assess their impact on network fragmentation and cohesion.
Main Results:
- Powerful clans occupy central positions in the marriage network.
- Alliances among less influential clans act as critical "load-bearing" ties, with their removal rapidly fragmenting the network.
- An inverted-U relationship was observed: clans with moderate bride-receiving shares (55-60%) exhibit the highest centrality, while extreme senders or receivers are peripheral.
- No statistically significant evidence supports status alone determining gendered exchange patterns, despite powerful clans having a slightly higher share of incoming brides.
Conclusions:
- Marriage functions as an organizational technology within the 'Ndrangheta, enhancing resilience through overlapping ties.
- Moderate gender asymmetries in marriage patterns optimize lineage consolidation and network brokerage.
- The organization's durability relies on both peripheral-to-peripheral alliances and unions of powerful families, highlighting marriage's dual role in cohesion and power management.
